We’ve seen Windows Phone Tango, build 8773, arrive pre-installed on phones like the Nokia Lumia 610, but what about it coming as an update to already-released models? A recent leak suggests that owners of the Lumia 710 on T-Mobile could be about to see Tango updates start arriving, while a new addition to Microsoft’s site has us thinking that the update could be nearly ready for other models, as well.

Microsoft has a new version of its Windows Phone update history page for its website, finally adding 7.10.8773.98 to the mix. For the moment, the new info isn’t available on the site’s English version, but it’s already being displayed for readers of some other languages; we see it here with Spanish. That’s not necessarily a direct indication that widespread Tango updates will soon commence, but it does add some circumstantial support to the theory.

What looks a little more certain is the news of a forthcoming Tango update for the 710, as revealed through a T-Mobile leak. According to the screencap, users will first gain access to the update on June 20, with distribution continuing through the end of July. In addition to Tango-specific changes like its new contact management system for SIM cards, the update will bring long-awaited WiFi hotspot support to the handset.
